"tuning fork" sensation in hands?

I searched for this here and on google and didn't really find much, mostly because I lack words to describe this.

Today after work I went for a ride totaling about 90 minutes. When I got off the bike afterwards I noticed my hands had basically become "tuning forks". If I hit them against anything, they vibrated, pretty much exactly like a tuning fork does. It was a very strange sensation and it lasted about 20 minutes.

I have an SV650S that has the clip on handlebars. They are, admittedly, not the most comfortable things in the world. But so far I have found them well within my tolerance level. I'm guessing the vibration of the bike combined with the position these bars put my hands in caused this? I don't "death grip" the bike at all, I think my grip is quite natural/normal.

Anyone experience this? Something to be concerned about? Anyone know if something like this can help prevent it?

I have experienced that. It's pretty common on twins and singles that transmit a lot of vibration to the grips. I tried bar end weights and didn't see much improvement. What worked best was high density foam grips, but even that didn't completely cure the problem on long riding days (6-8 hrs.).

+1 above

From the vibrations and possibly the way you lean on the grips -could be just the right spot to aggrvate. DH is currently having issue with the ST2 and his hands.

We're considering risers and possible change of grip.

Hmmm, ok, glad to hear I'm not the only one.

It didn't really bother me. Actually it felt kinda cool

I'm more wondering if this could be dangerous in the long run.

In addtion to was was mentioned above ( I guess that would be a +2 ) you could also try riding gloves with gel padded palms.

Well, the that fact that you're having sensation problems means that you're irritating your nerves. Over the long run, you could develop or incur some nerve damage, if not in your hand, but possibly up the wrist as well.

You might try adjusting the bars for a little different angle. You could also adjust the angle on your levers. These things may or may not help a little.

To actually help the vibrations you may need to change the resonant frequency between the bars and the motor. You could try the bar snake. I have heard of filling the bars with bbs or shotgun pellets. Bar end weights could work. Adding weight inside the bars creats a dampening effect.

Softer padded grips and/or gloves could also help.

Are you holding yourself up with the bars or your abdomen? This can also have an effect on you. Maybe changing your posture could help a little.
